💡TensorFlow Tip, use .prefetch

💡 #TensorFlowTip
Use .prefetch to reduce your step time of training and extracting data

• overlap the preprocessing and model execution
• while the model executes training step n the input pipeline is reading the data for n+1 step
• reduces the idle time for the GPU and CPU
